Opuladuo 2PC 12 Inch Chainsaw Chains for Dewalt 20V DCCS620B, DCCS620P1 Chainsaw

If you’re shopping for a replacement chain for a DeWalt 12-inch cordless saw, this Opuladuo 2-pack is intended for the DeWalt DCCS620B and DCCS620P1. Each chain is a 12-inch chain with 3/8” pitch, .043” gauge, and 45 drive links, which are the key fitment details to verify before ordering.

Will this chain fit your saw?

This chain is listed as a fit for these 12-inch saw models:

• DeWalt DCCS620B
• DeWalt DCCS620P1
• BLACK+DECKER LCS1240B
• BLACK+DECKER LCS1240
• CRAFTSMAN V20 CMCCS620M1
• CRAFTSMAN CMCCS620B
• Ryobi One+ P549
• Ryobi P548BTL
• RYOBI RY40509BTL
• Worx WG380
• Worx WG380.9

To confirm fitment, check all four chain specs on your current chain, bar, or saw manual:

• Bar length: 12”
• Pitch: 3/8”
• Gauge: .043”
• Drive links: 45

All four need to match. Bar length alone is not enough, because many 12-inch chainsaws use different chain configurations. If your saw is one of the models above and your original chain matches 3/8”, .043”, and 45 drive links, this replacement chain should be the correct size.

A quick note on drive links: this is the count of the links that sit down inside the guide bar groove. It is not the same as the number of cutting teeth. When in doubt, count the drive links on your existing chain or compare directly with the markings on your bar.

Replacing the chain

Before replacing the chain, remove the battery from cordless saws and make sure the chain brake is not accidentally engaged during handling if your saw uses one.

1. Remove the battery and place the saw on a stable surface.
2. Loosen or remove the side cover to access the bar and chain.
3. Take off the old chain, then clean sawdust and debris from around the sprocket area and bar groove.
4. Install the new chain on the bar and drive sprocket, making sure the cutter direction is correct. The cutting edges on the top of the bar should face forward toward the bar tip.
5. Reinstall the side cover and adjust chain tension so the chain sits snugly against the bar but can still be pulled around by hand.
6. Reinstall the battery, add bar-and-chain oil if needed, and test carefully at low load. Recheck tension after the first few cuts.

New chains commonly stretch slightly during initial use, so it’s normal to need a quick tension adjustment shortly after installation.

Keeping it sharp

A sharp chain cuts faster, puts less strain on the motor, and helps the saw feed smoothly through wood.

• Keep the chain properly tensioned. A loose chain can derail, while an overly tight chain increases wear on the bar and drive components.
• Maintain bar-and-chain oil. Running dry causes rapid wear to both the chain and the guide bar.
• Touch up or replace the chain when you notice fine sawdust instead of chips, slower cutting, or a tendency to make the saw pull to one side.

Avoid cutting into dirt, old fencing, or wood with embedded debris. Even a brief contact with abrasive material can dull a chain quickly.

FAQ

Will this fit any 12-inch chainsaw?
No. It is only suitable for saws that use a 12” chain with 3/8” pitch, .043” gauge, and 45 drive links. Matching the full chain specification is essential.

Does this page include one chain or two?
This product is listed as a 2-piece set, so you get two replacement 12-inch chains.

How do I know if my DeWalt saw is compatible?
If your saw is a DeWalt DCCS620B or DCCS620P1 and it uses a 12” chain with 3/8” pitch, .043” gauge, and 45 drive links, this is the listed replacement size.

Why is my new chain getting loose quickly?
That is common during break-in. A new chain can stretch slightly in its first use cycle, so check and retension it after a few cuts.
